noun

An organic compound formed by the condensation of two alcohol molecules with an aldehyde molecule.

'Its biologically active metabolites include acetal aldehyde which has been linked to ‘hangover ‘symptoms.’'

'The researchers have used supercritical CO 2 as medium for the conversion of alcohols to linear and branched ethers, to cyclic ethers, to aryl ethers and to acetals and ketals in good yields and, all-importantly, with high selectivities.'

'In addition, the use of specialty primers enables light-cure cyanoacrylates to develop strong bonds to polyolefins and other hard-to-bond plastics, such as fluoropolymers and acetal resins.'

'Experience in distilling aldehydes led us to believe that acetaldehyde would form acetals in the overheads of the low pressure column.'

((n.) A limpid, colorless, inflammable liquid from the slow
oxidation of alcohol under the influence of platinum black.)
